EnumProcessesback to summary
public boolean EnumProcesses(int[] lpidProcess, int cb, IntByReference lpcbNeeded)

Retrieves the process identifier for each process object in the system.
It is a good idea to use a large array, because it is hard to predict how many processes there will be at the time you call EnumProcesses.
To determine how many processes were enumerated, divide the pBytesReturned value by sizeof(DWORD). There is no indication given when the buffer is too small to store all process identifiers. Therefore, if pBytesReturned equals cb, consider retrying the call with a larger array.
To obtain process handles for the processes whose identifiers you have just obtained, call the OpenProcess function.

Parameters
lpidProcess:int[]

A pointer to an array that receives the list of process identifiers

cb:int

The size of the lpidProcess array, in bytes.

lpcbNeeded:IntByReference

The number of bytes returned in the pProcessIds array.

Returns:boolean

If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. To get extended error information, call GetLastError.

EnumProcessModulesback to summary
public boolean EnumProcessModules(WinNT.HANDLE hProcess, WinDef.HMODULE[] lphModule, int cb, IntByReference lpcbNeeded)

The EnumProcessModules function is primarily designed for use by debuggers and similar applications that must extract module information from another process.
If the module list in the target process is corrupted or not yet initialized, or if the module list changes during the function call as a result of DLLs being loaded or unloaded, EnumProcessModules may fail or return incorrect information.
It is a good idea to specify a large array of HMODULE values, because it is hard to predict how many modules there will be in the process at the time you call EnumProcessModules.
To determine if the lphModule array is too small to hold all module handles for the process, compare the value returned in lpcbNeeded with the value specified in cb.
If lpcbNeeded is greater than cb, increase the size of the array and call EnumProcessModules again. To determine how many modules were enumerated by the call to EnumProcessModules, divide the resulting value in the lpcbNeeded parameter by sizeof(HMODULE).
The EnumProcessModules function does not retrieve handles for modules that were loaded with the LOAD_LIBRARY_AS_DATAFILE or similar flags. For more information, see LoadLibraryEx.
Do not call CloseHandle on any of the handles returned by this function. The information comes from a snapshot, so there are no resources to be freed.
If this function is called from a 32-bit application running on WOW64, it can only enumerate the modules of a 32-bit process.
If the process is a 64-bit process, this function fails and the last error code is ERROR_PARTIAL_COPY (299).
To take a snapshot of specified processes and the heaps, modules, and threads used by these processes, use the CreateToolhelp32Snapshot function.
Starting with Windows 7 and Windows Server 2008 R2, Psapi.h establishes version numbers for the PSAPI functions.
The PSAPI version number affects the name used to call the function and the library that a program must load.
If PSAPI_VERSION is 2 or greater, this function is defined as K32EnumProcessModules in Psapi.h and exported in Kernel32.lib and Kernel32.dll.
If PSAPI_VERSION is 1, this function is defined as EnumProcessModules in Psapi.h and exported in Psapi.lib and Psapi.dll as a wrapper that calls K32EnumProcessModules.
Programs that must run on earlier versions of Windows as well as Windows 7 and later versions should always call this function as EnumProcessModules.
To ensure correct resolution of symbols, add Psapi.lib to the TARGETLIBS macro and compile the program with -DPSAPI_VERSION=1.
To use run-time dynamic linking, load Psapi.dll.

Parameters
hProcess:WinNT.HANDLE

A handle to the process.

lphModule:WinDef.HMODULE[]

An array that receives the list of module handles.

cb:int

The size of the lphModule array, in bytes.

lpcbNeeded:IntByReference

The number of bytes required to store all module handles in the lphModule array.

Returns:boolean

If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. To get extended error information, call GetLastError.
